Cannot create new c++ project. Engine 4.26.2

I had the same or a similar problem (Linux Debian 11), and found in various places that others encountered it, too. Seems to be the editor/project manager not reading its environment correctly and thus cant find its components.

Couldn’t solve it in reasonable time.

Epic should deliver a simple C++ code editor built into the engine, doesn’t have to be big thing, or at least they could document the setup, what configuration OS-wise has to happen prior to starting a new project or, if that exists in some data vault, link to it on the tutorial pages.
